A TTOP/YE Y United States Patent O 2,754,781 NECKTIE SEWING SYSTEM Victor M. Newman, New York, N. Y. Application February 19, 1954, Serial No. 411,354 8 Claims. (Cl. 112-174) This invention relates to necktie sewing apparatus.

Machines for sewing neckties have taken various forms including those of the slip-stitch type. In such machines an enlongated needle is caused to traverse substantially the entire length of the necktie farbric and its lining after both have been crimped along a longitudinal seam to be sewn. The thread of the needle thereby produces spaced stitches known as slip-stitches which sew the necktie fabric to its ultimate shape while connecting it to the lining.

Any neckties made pursuant to such slip-stitch machines and in fact, in any other machines of which I am aware, are sewn along an inside seam which is exposed at the time of sewing so that the sewn tie must be reversed to bring the right side out.

With the above in mind, it is an object of the present invention to produce a necktie sewing apparatus, preferably of the slip-stitch type, which avoids the necessity of turning the sewn tie inside out. In other words, the tie is sewn from the inside while it is in its ultimate state, i. e., the right side of the fabric on the outside.

I accomplish the foregoing by employing suitable temished form and at the same time are employed to guide the fabric edges between crimping teeth which are arranged to be disposed within the formed fabric. Such crimping teeth are provided with complementary and nter-fitting recesses which form An elongated needle is employed to traverse the needle path and to sew the necktie fabric edges as well as the lining from within the formed necktie so that the tie need not be reversed. The mechanism is moreover of pronounced simplicity and effects considerable manufacturing economies.

after it is removed from the form.

Lower template 25 also includes a side portion 29 which also comprises wider ends and has an edge which is complementary to edge 27. Side portion 29 is connected to center portion 26 by hinges 30, the construction of which will be hereinafter described.

To the edge 28 of center portion 26 is hingedly secured side portion 31. In view of the curved nature of edge 28, side portion 31 is slitted at 32 and 33 so as to facilitate swinging action thereof over center portion 26 as will be hereinafter described more fully.

Figure 2 illustrates the upper template 35 which is provided with opposed rows of crimping or corrugating Template 35 comprises a wider portion are in V-shaped 37 are designed the teeth 36, the 42 of teeth 36.

to be superimposed over, and mate with mg slots or recesses, if required, may be ascertained from my prior Patent 2,608,170 issued August 26, 1952, as well as my patent application Serial No. 152,445 filed March 28, 1950, now Patent No. 2,678,618. The row of teeth crests of teeth 37 fitting into the valleys` 36 continues along and past the end of portion 38 to form a hinged arm 44, the hinge 45 connecting it to the bar 46 which is secured to a table or other support. To the same support is secured template as by the bolts 47. Template is normally superimposed and lying upon template 25, the hinge permitting template 25 to be lifted relative thereto or to be laid tiatly thereon.

Only the templates of Figure 1 and Figure 2 are required in producing a necktie and the operation thereof will now be described:

After swinging the template 35 upwardly, the tie fabric 59 is placed upon the lower template 25 as illustrated in Figure 3, the wrong side of the fabric being uppermost. It will be noted that the dimensions of the fabric are uniformly greater than those of the lower template in all directions. The upper template 35 is then lowered over the fabric. In this position, the hinged edges 4) are directly above the hinged edges 27. The lining Si is then disposed over the wider template portion 3S, the lining 51 substantially conforming to the shape of such wider portion 38. It will be recognized, of course, that the lining 51 is disposed directly over the row of corrugating teeth 36.

Narrow side portion 31 of the lower template 25 is now swung over, all three sections thereof being swung, so that it is caused to overlie the lining while the edge 52 of the tie fabric is brought over the row of teeth 36, which is actually covered by the lining 51. Accordingly, it will be recognized that thus far both the lining and the fabric edge 52 are disposed over the row of teeth 36. In the next step the side portions 29 and 39 are folded in unison along their respective hinged edges 27 and 40. Actually, as noted in Figure 4, while side portion 39 is disposed directly over side portion 29, it is narrower than side portion 29, the side portion 39 extending further outwardly. However, inasmuch as they are superimposed and are swung about axes or hinge lines which are superimposed, the extreme outer edge 53 of the side portion 39 is caused to approach the edge 54 of side portion 29. In other words, narrow side portion 39 swings about a smaller radius and its outer end accordingly travels upon side portion 29, approaching its outer edge.

The outer edge 54 of side portion 29 is formed with an inward hook or re-entrant portion 55 as noted in Figure 8. Accordingly, when the extreme outer edge 53, during the swinging action, travels upwardly relative to, or towards the edge 54, it forces the corresponding edge 56 of the tie fabric into substantially U-shaped form to such an extent that it is brought around or over the row of teeth 37. it will now be recognized that when the rows of teeth meet and mate, all the conditions for slip-stitch sewing will have been achieved. In other words, as noted in Figure 9, the center of the tie lining and the respective edges 52 and 56 of the tie fabric are superimposed and are disposed between the corrugating teeth 36 and 37 which urges the superimposed portions into crimped form as illustrated in Figure 10. ln Figure 9, it will be recognized that such edges 52 and 56 are spaced inwardly from the exterior-most layer ofthe fabric so that the needle may pass through such interiorly located edges only and not through the exterior-most layer. It is only necessary to now force the elongated needle 60, having the thread 6l, through the full extent of the aligned needle path so as to accomplish the required stitching of the tie.

Reference may here be made to the form of the hinges between the template portions which are best illustrated in Figure 8. Hinges 59 are provided at spaced points along the edges 40 and such hinges comprise simple hinge pins in hinge sockets. However, the hinges 3i) should be somewhat differently constructed inasmuch as the folded template 25 must embrace the folded template 35. Accordingly, hinges 30 take the form of links which provide the folded template 25 with a substantially straight side accommodating the hinge 59.

When the apparatus and the tie fabric and lining are in the condition shown in Figure 9, the tic fabric is folded to its substantially finished form with the right side of the fabric on the outside and the fabric in its substantially attened tubular state. At this time an elongated needle 60 (Figure 10) may be directed through the aligned needle path formed by the complementary recesses of the corrugations. Such action is conventional per se and is explained in my above mentioned prior patent. As will be noted from Figures 9 and 10, the edges of the fabric and the lining are sewn together and the seam then occurs on the inside of the tie so that the tie need not be reversed.

The tie in its finished state is formed around the upper template 35. It is only necessary to unfold the lower template 25 and merely slide the finished necktie over the smaller, left-hand end of the upper template 35 loosening the grip of the teeth if necessary. lt will be observed that the smaller end of the template flares outwardly or is wider than its center so that the removal of the formed necktie from the template would seem to create some problem. Actually however, the tie fabric is resilient and the center or narrow portion of the formed tie can easily slide past the slightly wider end of the template.

The remaining figures are directed to a modification of the apparatus above described. Thus, Figure 12 discloses a modied form of upper template. Said upper template is a symmetrical structure formed of four walls 71, 72, 73 and 74 as noted in Figure 19. Walls 73 and 74 are heavier and overlie the walls 7l and 72 as illustrated in Figure 19. These walls, as all the walls of the templates described herein, are preferably metallic. Lower walls 71 and 72 are connected by a longitudinal hinge 75. Upper wall 73 is connected to lower wall 71 by hinges 76. Upper wall 74 is connected to lower wall 72 by hinges 77.

Template 7i) in its planar position, is illustrated in Figures 12 and 18. I refer to the template 7) as being planar when its top walls 73 and 74 are in horizontal surface alignment rather than being inclined toward each other as illustrated in Figure 19. The inner edges of the upper walls 73 and '74 are terminated in peripheral, complementary, corrugating teeth Si? which are designed to mesh with each other. However, when the template 70 is planar as illustrated in Figure 18, the teeth do not mate but are spaced from each other to a slight extent. As will be hereinafter shown, it is by swinging action along the hinge 75 that the walls 73 and 74 are inclined toward each other and the teeth are caused to mate.

The teeth are formed with mutually aligned recesses to form a needle path as will be hereinafter pointed out more clearly.

The lower template 81 comprises a four element structure designed to embrace the folded template 70. Central portions 82 and 83 conform to the configuration of template 70. The elements of template S1 are hingedly connected together as by hinges 34, 85 and 36. Further, the end portions S7 and 88 are transversely slitted as at 89 in order to facilitate the folding operation as will be hereinafter described.

The apparatus of the modified embodiment is employed as follows:

The lower or outer template 81 is laid down in planar form as illustrated in Figure 18 and the necktie fabric 90 with the wrong side up is placed thereon as illustrated in Figure 14. The upper template in its folded form is placed over the fabric and directly over the central template portions 82 and 83 which it tits almost exactly. This is illustrated in Figures l5 and 18. It will be noted in Figure l5 that the teeth comprise separated rows of corrugations 91 and 92. The lining 93 is slipped between these corrugations so that half appears over one row of the corrugations and the other half is disposed between an upper wall and a lower wall of the upper template. This is illustrated in Figure 18.

The outer edges of the outer template portions 87 and 88 are formed with flanges 94 and 94a which, as noted in Figure 19 are substantially at right angles to the walls 73 and 74 respectively. The outer portions 87 and 88 of the lower template are folded over the upper template and the flanges 94 and 94a thereby force the outer edges 95 and 96 of the tie fabric into the space 97 between the rows of teeth. This is illustrated in Figure 19.

The apparatus is designed to bring the teeth together at this time, the hinge 85 serving this function. As will be noted in Figure 19, the hinge 85' of the lower template as well as the hinge 75 of the upper template permits both halves of the structure to be brought toward each other to close up the space 97 by inclining the walls 73 and 74 toward each other. This causes the edges 95 and 96 to become crimped together with the central portion of lining 93 and a needle path is formed as illustrated in Figure 20. The mating recesses are formed across each tooth and they are staggered in the respective rows to form an aligned slot or needle path. The elongated needle is then forced through the needle path to sew the tie.

When the sewing has been completed it is merely necessary to fold back the lower template, restore the upper template to a planar position so as to separate the teeth and then merely slip the finished tie over the narrower end of the upper template, the resilient nature of the tie fabric permitting the narrower central portion thereof to stretch slightly and permit its removal from the slightly wider end.

As above set forth, the tie is now in its finished form and need not be reevrsed inasmuch as the sewn seam is on the inside.
